I asked her to join the team after it became clear that our lead developer could not implement the required functionality on time or in a quality manner. Olga quickly apprehended the underlying architecture of the product (which was not well documented), quickly fixed bugs from earlier work, and then proceeded to implement new features in an elegant and efficient manner.Olga understands the many subtleties associated with complex AS3 projects, makes excellent suggestions on how to improve a design, and performs her work in a timely manner.I look forward to hiring Olga again on future projects.”
